Hi,
I have been programming in Squeak3.10.2 for 10 years. Squeak 3.5 is a 
great improvement from the old 3.10.2 and it is time to update all my 
programs. There is a new VM that is different from the old. I'm used to 
letting the file extension identify the appropriate program for handling 
a file so I want to use a new file extension, /.image3/, for the /Squeak 
Cog Spur Virtual Machine/.

  It transpires that the String '.image' is embedded in any number of 
methods. In my Fortran days,  we learned to avoid embedded constants 
because they had a tendency to change. (E.g., '3.14' to 
'3.14159265358979323846' because we needed higher precision.)

Should I try to replace all embedded '.image' with a method call, e.g., 
Smalltalk imageExtension?
